What is the relation between magnetic flux and current? Sample Answer: The magnetic flux density through a coil is directly proportional to current. When the current increases the magnetic flux density will increase. What is electromagnetic induction What are the ways to induce current in a coil? Electromagnetic or magnetic induction is the production of […]
How can I get hydrated quickly?

While it likely comes as no surprise, drinking water is most often the best and cheapest way to stay hydrated and rehydrate. Coffee and tea. Skim and low fat […]
How far should your house be from power lines?
How far should your house be from power lines? For 133 kV Power lines you have to maintain 100 feet distance. For 230 kV Power lines you have to maintain 150 feet distance. For 345 kV Power lines you have to maintain 250 feet distance. Is it dangerous to live near power transformers? Most scientists […]
What is the formula for frequency of light?
What is the formula for frequency of light? Divide the speed of light, ~300,000,000 m/s, by the wavelength in m. This gives you the wave’s frequency. What is the frequency of red light? around 430 terahertz Does blue or red light have a higher frequency? Blue light has shorter waves, with wavelengths between about 450 […]
What is explosion in class 8?
What is explosion in class 8? CBSE NCERT Notes Class 8 Chemistry Combustion and Flame. The type of combustion reaction that occurs with the evolution of tremendous amount of heat, light, gases and sound is known as Explosion. For instance, when we burn a cracker it bursts with the liberation of tremendous amount of heat, […]
Is energy transferred when two atoms collide?
Is energy transferred when two atoms collide? These atoms frequently collide and transfer energy between one another. Therefore, when two atoms collide and start to oscillate, some energy may be transferred to other particles by collisions. If this happens, a stable interaction can form between the two particles; they will “stick” together. At what point […]
Why do water bottles have an air hole?
Is viscosity dependent on temperature?
Is viscosity dependent on temperature? According to the kinetic theory of gases, viscosity should be proportional to the square root of the absolute temperature, in practice, it increases more rapidly. With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same. Does salt increase surface tension? Yes, adding […]
What are the types of vesicular transport?
What are the types of vesicular transport? Vesicles or other bodies in the cytoplasm move macromolecules or large particles across the plasma membrane. There are two types of vesicle transport, endocytosis and exocytosis (illustrated in Figure below). How can you prevent endocytosis? To avoid the problem of non-specific effects of chemical inhibitors, genetic approaches have […]
How do you calculate Macrostates?
How do you calculate Macrostates? The probability of finding any given macrostate is the ratio of the number of its microstates to the total number of possible microstates. For example, the probability of getting 2 heads is W (n)/ W (all) = 3/8. Things get more tricky if you have many coins, like 100, for […]
